We find that VKT increases proportionately to highways and identify three important sources for this extra VKT: an increase in driving by current residents; an increase in transportation intensive production activity; and an inflow of new residents. The provision of public transportation has no impact on VKT. We also estimate the aggregate city level demand for VKT and find it to be very elastic. We conclude that an increased provision of roads or public transit is unlikely to relieve congestion. aHardcopy version available to institutional subscribers. aSystem requirements: Adobe [Acrobat] Reader required for PDF files. aMode of access: World Wide Web. 7aL91 - Transportation: General2Journal of Economic Literature class. 7aR41 - Transportation: Demand, Supply, and Congestion • Travel Time • Safety and Accidents • Transportation Noise2Journal of Economic Literature class.1 aTurner, Matthew A.2 aNational Bureau of Economic Research. 0aWorking Paper Series (National Bureau of Economic Research)vno. w15376.4 uhttp://www.nber.org/papers/w1537641uhttp://dx.doi.org/10.3386/w15376
